Abstract:

Based on data of log, core and seismic profile, the sedimentary system and sedimentary facies of H31 ofHetaoyuan Formation in the south of Xia+ermen Oilfield of Biyang Sag are analyzed. There are three kinds ofsedimentary systems, including delta, fan delta and lacustrine system. The types of the sedimentary facies combiningwith the thickness map of sandstone are applied to analyze the source channel and direction.

Key words: lithologic trap, fullness degree, main controlling factors, quantitative model, West Sag
